Abstract
Relationship between electron beam parameters (energy, energy spread, and electron beam distribution in irradiation zone), electrical cable geometry (thickness of polymer layers and metal wire diameter), construction (jacked, insulation) and dose distribution represented by the Dmax/Dmin coefficients were investigated. The simulations were performed using ModeCEB computer program (Lazurik et al., 2011) and then compared with the experimental data. It was demonstrated that computer simulations based on the ModeCEB program are sufficient for modeling absorbed dose distribution in the multi-layers circular objects irradiated with scanned electron beam. The calculations revealed (1) significant inhomogeneous circumferential dose distribution in polymeric sub-layers (2) relatively low influence of electron beam energy spectrum on homogeneity of irradiation and (3) high influence of beam divergence on the circumferential dose distribution.
